Later Archaic Greek gems: inscriptions

Few gems have been found to be inscribed, with the name of their maker or their owner, the latter generally being more conspicuous. They must have been used for sealing as well as being worn as jewellery, on swivel rings or pendants, but few reveal this as well as:

Agate scarab from Aegina. Small dolphin and the inscription 'I am the seal (sama) of Thersis; do not open me!'
